Hoplitaspis hiawathai, specimens preserving morphological details of the prosoma and opisthosoma. a UWGM 2280, large specimen preserving the full opisthosoma, including the buckler ventral plate, and robust prosomal appendage podomeres. b UWGM 2700, almost complete specimen preserving the lateral and median eyes, prosomal appendage armature, and opisthosoma. c UWGM 2276, specimen showing the prosomal appendages and gnathobases. d UWGM 2273, block preserving multiple specimens. UWGM 2273A displays details of the lateral eyes and prosomal appendages, UWGM 2273B affords a view of the ventral buckler plate, UWGM 2273C reveals the coxa of the prosomal appendages in situ anterior to the prosomal ventral plate, and UWGM 2273D displays a lateral view of the prosomal shield revealing the ventral expansion of the prosoma surface and the wide field of view of the lateral eye. Scale bars = 10 mm
